It remains Canada's deadliest mass killing.
VANCOUVER, British Columbia (Reuters) - Canada was warned of a plot to bomb an Air India jetliner months before the 1985 attack that killed 329 people, but police failed to act on the information, a hearing was told on Monday.
The June 23, 1985, bombing of Air India Flight 182 over the Atlantic Ocean was history’s deadliest bombing of a civilian airliner.
